This manual enables safe and efficient handling of the high pres-

sure valve.

The manual is a component of the high pressure valve and must

be kept in the vicinity of the high pressure valve where it is avail-

able to personnel at all times.

The personnel must have carefully read and understood this

manual before performing any tasks. The basic prerequisite for

safe work is compliance with all the specified safety notices and

instructions.

In addition, the local occupational safety regulations and general

safety regulations must be complied with for the high pressure

valve’s area of use.

The illustrations in this manual are provided as examples only and

may deviate from the actual version.

Although the size and pressure ratings of the valve

types vary, the information in these instructions

applies generally to all valves, provided nothing to

the contrary is specified.

This manual applies to the following versions of the high pressure

globe valves:

1 Overview

Fig. 1: Overview - high pressure globe valve

The valve designated as high pressure globe valve is designed for

installation in pipes.

With the high pressure globe valve, depending on the version, it is

possible to

nshut-off or

nregulate

the pumping medium flowing through the valve.

The body (Fig. 1/2) of the valve is flanged or welded in the pipe-

work, depending on the version.

In the closed position, the shut-off element (Fig. 1/1) prevents the

pumping medium from flowing through the valve.

If the high pressure globe valve is used for regulation, the flow of

the pumping medium is influenced by the position of the shut-off

element.

globe valve

Overview

The shut-off element is driven in or out via the stem. Depending on

the version, the stem is activated (Fig. 1/3) manually via a hand-

wheel (Fig. 1/4) fixed to the bonnet (Fig. 1/5), electrically, hydrauli-

cally or pneumatically.

The following tools are required for the tasks described in the oper-

ating manual:

Forklift

Forklift with sufficient load-bearing capacity for transport of valves.

Hoist

Hoist with sufficient load-bearing capacity for transporting valves

and components.

Hook wrench

Hand tool for activating the threaded bush or mounted electric

actuator.

Knock-out tool

Pin-like tool for driving the tension pin out of the stem.

Mounting sleeve

Sleeve for mounting and dismounting the stem for valve versions

with backseat.

Sling gear

Functional and approved gear for attaching valves and compo-

nents on the hoist.

Spacers

Spacers for use during the separation of bonnet and body.
